1. What is the Absolute CVD Risk Calculator?

The Absolute CVD Risk Calculator Australia estimates an individual's 5-year risk of developing cardiovascular disease (CVD) based on key risk factors including age, blood pressure, cholesterol levels, smoking status, and diabetes. This tool helps healthcare professionals assess overall cardiovascular risk rather than focusing on individual risk factors.

2. How Does the Calculator Work?

The calculator uses the Australian CVD risk model:

\[ Risk \% = f(Age, SBP, Cholesterol, Smoking, Diabetes) \]

Where:

\( Age \) — Age in years
\( SBP \) — Systolic Blood Pressure (mmHg)
\( Cholesterol \) — Total cholesterol (mmol/L)
\( Smoking \) — Current smoking status (yes/no)
\( Diabetes \) — Diabetes status (yes/no)

Explanation: The algorithm integrates multiple risk factors to provide a comprehensive 5-year cardiovascular disease risk assessment based on Australian population data.

3. Importance of CVD Risk Assessment

Details: Comprehensive CVD risk assessment allows for better targeting of preventive interventions and helps guide clinical decisions regarding lifestyle modifications and pharmacological treatments.

4. Using the Calculator

Tips: Enter age in years, systolic blood pressure in mmHg, cholesterol in mmol/L, and select smoking and diabetes status. All values must be valid and within reasonable clinical ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is considered high CVD risk?
A: Generally, 5-year risk ≥15% is considered high, 10-15% moderate, and <10% low risk, though thresholds may vary by guidelines.

Q2: How often should CVD risk be assessed?
A: Every 2 years for people aged 45-74 years without known CVD, or more frequently if risk factors change significantly.

Q3: Are there populations where this calculator shouldn't be used?
A: Not recommended for people with existing CVD, very high single risk factors, or certain conditions like chronic kidney disease.

Q4: What's the difference between absolute and relative risk?
A: Absolute risk shows the actual probability of developing CVD, while relative risk compares risk between different groups.

Q5: How accurate is this risk prediction?
A: The calculator provides population-level estimates; individual risk may vary based on additional factors not included in the model.
